摘要： Glyoxal may be produced with a high yield by bringing a gas, which has been formed by diluting ethylene glycol and molecular oxygen with an inert gas, into contact at a high temperature with a silver catalyst in the simultaneous presence of phosphorus or a phosphorus compound so as to effect the gas phase oxidation of the ethylene glycol.In the above process, it is possible to suppress the formation of glycolaldehyde, a reaction intermediate, and also to enhance the stability of the reaction by using silver powder having particle sizes of 1.times.10.sup.-3 mm or smaller as at least part of the silver catalyst.

摘要： A process for preparation of nitrous oxide, wherein ammonia is reacted with oxygen in the presence of steam using a copper-manganese oxide catalyst having diffraction angles measured by X-ray diffraction analysis of about 36.degree., about 58.degree. and about 64.degree.; a copper-manganese oxide catalyst suitable for the process. The catalyst is highly active and selective, has a long catalyst-lifetime, gives a non-condensable gas comprising nitrogen, oxygen and nitrous oxide which contains nitrous oxide in a high concentration, and is less deteriorative. The catalyst can be used in a process for preparation of nitrous oxide in which formation of NOx as by-products is reduced; and a process for stably recovering nitrous oxide.
